Deb, we have some of the plants you mentioned but others are terribly invasive up here. And Devil's Club. Yechhh.
You get into that stuff and you would be miserable for weeks with itchiness and burning. But it might work differently down there. We find Lily of the Valley to be also terribly invasive. You can rip it out where you don't want it though. I have False Solomon's Seal, about 2' tall on slender bending stalks that have lovely little bell shaped flowers dangling in a row. White with the faintest green edging. My mother in law thinks it is creepy and weird but it comes back each year and slowly spreads. I dug some corms (don't know what you would call them - bulbs similar to Chocolate Lily bulbs) and planted them next to the house on the west side where they only get sun in the afternoon which is really hot in summer. So a difficult place to plant. No sun at all then hot direct sun. Bleeding Heart, Goat's Beard, Leopard's Bane, short columbine and Hosta all do well there though. That is one of the areas I was looking for a ground cover for. The Kinnikinnik might work well there as a sort of edging in the front. Although it would look kind of strange with some Hosta mixed in. Weird mix.
